Whaaat?? I had no idea it had been renewed. Going to have to remember how I watched the lasr season since I don't think we have AMC now. Maybe YouTube?

YouTube has some trailers and such up for free, but appears to be charging--a LOT, $50 per month!!--to see the entire season. If you time the two-week free trial right you might be able to see all ten episodes of season 4, after they've aired on AMC, presumably.
